36. on the moon’s surface, lunar astronauts placed a corner reflector, off which a laser beam is periodically reflected. the distance to the moon is calculated from the round-trip time. what percent correction is needed to account for the delay in time due to the slowing of light in earth’s atmosphere? assume the distance to the moon is precisely 3.84×108m and earth’s atmosphere (which varies in density with altitude) is equivalent to a layer 30.0 km thick with a constant index of refraction n=1.000293.

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 °c, what is the final temperature? note that 1 lb = 453.6 g.
